A safety data sheet (also known as MSDS sheets or PSDS product safety data sheet) is a form with data regarding the properties of a particular substance and may include instructions for the safe use and potential hazards associated with a particular material or product.
SDS are intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner. They include information such as physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill-handling procedures. SDS formats can vary from source to source.
